EXTRACTR.

' To alla/ihm 'it may concern.'

Be it known that l", .lons H. Chemise, a citizen of the United States, residing at Gulfport, in the county 'of Harrison and State of Mississippi, have invented new and useful Improvements in Extractors of which the following is a specification.

This invention relates to tnrpentine and .rosin extractors, and its object is to provide an extractor whereby the natural solvent of the rosin (turpentine) may be ntilized for its extraction and the objections inci-` 4 dent to the use of high pressnre steam and hydro-carbone or other foreign solvents avoided. A

A further object of the invention is to provide an extractor whereby the tnrpentine may be rapidl)7 and economieallyieitracted from the Wood and whereby a greater onantity and higher grade of tnrpentine may he obtained 'from a given ernennt of material than by the use of any or' the ordina@T proe- ESSQS.

The invention eansists of the features of construction, combination and arrangement of parts hereinafter fully described and `v claimed, reference being had to the accom- Ktolse treated is fed into the extractor. The

door l seats against a ange 7, 'iforming a tight joint to prevent esca, of the stearn and volatile products, which latter upon their liberation frein the material discharge through a pipe 8 having a controlling valve 9 to a suitable condenser.

The'casing orcylinder 1 is provided with an upper ixed'dome-shsped bottom head 10 and a lower removable bottom head 11, which are relatively spaced to form an intervening steam chest or heating chamber 12. The head 11 is provided with a ange 13 which fits riotionally Within the lower end of the Speccation oi' Letters latent.

casing, thus permitting said head to he removed Whene'. er occasion requires, for access to the interior of said chest or chamber.

Communicating vvith the chest or chamber 12 through the head 11 is a steam supply pipe 14 having a controlling valve.15, and also communicating with said chamber through said head is an exhaustA pipe 16 having a controlling valve 1'?. The pipe 14 is provided for supplying live steam to heat the chamber 12, while the pipe 16 permits off the drainage or? of any water of condensation, and is also adapted by the opening of the valve 13'" to permit of a regulated exhanst of steam therefrom to maintain an even teinperatnre within the chest or chamher. coupling i8 communicates with Ithe upper portion oi the chamber 12 through 10 and is in the orm of aV controlvave h ving a stern projectin 'vardlv through a stalling box 20, Whic pro-v veits leakage vapors to the exterior.

arranged within the outer casing or cylin der 1 isy a perforate cage or basket 21, hav- Y.

ing a perforate botton122, said cage `or baslieti being arranged to rest at its base upon a flange 23 secured to the interior ofthe casing. rlhis cage or basket is designed to receive the body of comminuted wood to be treated and is disposed in spaced relation to the casing to provide an intervening annular passage Le For the'diechargeof the volatile constituents liberated from the Wood and free passage of the saine to the pipe 8,

the liberated resin grevitating downward through the perforste bottom 22 end entering a collection chamber 25 ormeil between the same and the head i0.

At its lower end the casing 1 is provided with an outlet 26 Acorrinmnicating with an opening 9,?` in the cage, through which the body of coinminuted Wood after treatment may be raked or otherwise discharged from th'e cage. rihe outlet or manhole 27 is closed by e door or cover 28 Secured in position by swing bolts 29 having clamping nuts 3Q and resting against a gasket 31 to maintain a steam and vapor tight joint. A pipe 32 communicates with the chamber 25 for the withdrawal of the rosin and Water of condensation from the steam associated therewith, and said pipe is provided with a controlling valve 33.

Extending centrally and long-itudiua'llJfV manera at the base oif the casing beine: said extracting chamber and cosed against communication therewith, and a resin ceilection charnber between said extracting and heating chambers, a perforated inner receptacie disposed within the extracting chamber, said receptacle being spaced at its sides from the casing to provide a surrounding vapor outh let and being in Comunication with said resin coliection chamber and through its perforations at aii levels in communication with the vapor collectionA space, means for suppiying steam to the heating chamber, a perforated steam injection pipe communicating 15 lwith the heating chamber and extending centrally and upwardly through the per` orated receptacle to the top thereof, a soivent supply pipe, Ya solvent heatin coil conimunicating with said pipe an Within the heating chamber, a solvent discharge coil communicating with the top or" the perforated receptacle, and a conductin connection between saidsoivent heating coiand solvent discharge coil. Y 2. An extractor comprising an outer inclosing casing having a valved Vapor discharge outiet at its top, a heating chamber at its bottom and a resin collection charnber above said heating chamber, said coi iection chamber being provided with 'a vaived outlet, a perforated cage arranged Within the casing above said coiiection cham ber and in spaced reiation to the casing,` perforated Secam injection pipe disposed within the chamber, a solvent inj @einer within tbe top o the cage, a heating eoii within the beating chamber, eoii ,being in coniniunicaion with said injector, means ior disposed supplying sieani to the heating chamber, and means for sappig/ing a solvent to the coil for delivery to the injector.

3. An extractor comprising an outer inciosing casing,a having a waived vapor die: charge outiet at its top and a refuse outiei; at a point' above its bottom, a dome-shaped partition between the bottom of the casing and saidL outlet, said partition forming a heating chamber closed against communlcation with the casing7 a second perforated partition arranged above said dome-shaped partition. and providing therewith' a rosin collection space, a Valved` rosin discharge out iet ieacling from said space'steam supply and exhaust pipes communicating with the heat ing chamber, a perforated cage arranged Within the casing and supported by said per iorated partition in spaced relation to the casing, said cage being,n in communication with said refuse outlet, a perforated seeam suppiy pipe communicating at its lower end wiii the steam supply chamber and extending axially through the cage to a point at or near the top thereof, a valve controlling the ow of steam to said perforated pipe from the heating chamber, a solvent spray coil disposed within the to of the cage, a heaiing coii disposed Wit 1in the heating cnaniber, ascii/ent conducting pipe connecting said. colis, and a solvent supply pipe connected with the latter named coiln in testimony whereof Ii a@ my signaeure in presence of two witnesses.
